umm mabey fake card sorry were you get it because i just sent a fake iedge back and got a real one off www.all4consoles.co.uk so see what website it says on the back of the box because if it says www.edgei-ds.cn then its a fake and send it back.
Reformat your MSD with Panasonic Formatter, download the newest firmware (iEDGE OS v1.9i) from this site: http://www.edge-ds.cn/download.html Copy all the files to the root. Now it must play fine.
